Auth Manager Setup

Configure the authentication manager with storage options and auth methods

See SDK Reference for more details on the Auth Manager. Auth Manager Reference

Overview & Key Concepts

The Auth Manager handles authentication flows and session persistence.

AuthContext Creation

This method caches two components:

Session Key Pair: A temporary cryptographic key pair generated on the client side that acts as a temporary identity for the client application. It consists of:

• Public key - shared with the Lit nodes
• Secret key (private key) - kept securely on the client

Delegation AuthSig (Inner Auth Sig): A cryptographic attestation from the Lit Protocol nodes that authorises your session key to act on behalf of your PKP

1. Install the SDK

   Run the following command to install the SDK:

   npm

   npm i @lit-protocol/auth@beta
   

2. Choose Storage Plugin

   Choose the appropriate network based on your development stage and requirements, then create your Lit Client instance.

   browser

   import { createAuthManager, storagePlugins } from "@lit-protocol/auth";
   
   const authManager = createAuthManager({
     storage: storagePlugins.localStorage({
       appName: "my-app",
       networkName: "naga-dev",
     }),
   });
   

Storage Options Comparison

Select the appropriate network environment based on your development stage and requirements. Each network offers different characteristics for testing and production use cases.

Storage Type	Persistence	Use Case	Environment
localStorage	Survives page refresh & browser restart	Web applications, client-side storage	Browser
localStorageNode	File-based persistent storage	Node.js applications, server-side scripts	Node.js only
custom	Depends on implementation	Database storage, encrypted storage, cloud storage	Custom
